uncovered by an fbi investigation into a series of e-mails sent by his biographer, paula broadwell, who was accused of sending harassing e-mails to another woman. that sparks an investigation that revealed her secret relationship with petraeus. but after looking at a recent speech she gave on the death of four americans in libya, people started wondering whether she and petraeus had shared any classified intel and whether she inadvertently spilled some of those secrets during her remarks. bill gross joins us live, what's your impression of this situation as it's playing out? >> well, it's certainly a very interesting situation, as you say. there's a joke going around on twitter that the french intelligence director resigned because he doesn't have an affair for six months. so the idea that an extramarital affair in itself would bring down the cia director is very isn't in my mind. there has to be more to the story. my guess is it has to do with internal cia politics. the agency's known to be using intelligence information to settle scores, or it could be related to the benghazi scandal.
